Miguel Gutierrez and the Powerful People are presenting a roughly half-hour excerpt from their upcoming premiere, I Succumb, as part of DTW's SplitStream program (through May 20). So what is this thing called love? A grim rectangle of light where denim-clad dancers collapse and creep around, becoming violently entangled with one another's bodies as Jaime Fennelly's music snaps, crackles, and pops. Pelvises pump frenetically, limbs gyrate helplessly, and dancers split apart like cells in mitosis. Later, members of a tidy lineup gently maneuver any strays back into order, and partners move in a brisk, expressionless duets. The company certainly earns its unusual name through these forceful performances. Other interesting ensemble works share the bill: Worthless Limbs, by Luciana Achugar and Levi Gonzalez; and Paul Matteson's Failing Me Now, with its standout solo, sort of an anthropomorphized heart arrhythmia, for dancer Lisa Gonzales.
